The protection of physical assets from unauthorized access, damage, or interference.
Description
Physical security refers to the measures taken to protect physical assets like buildings, equipment, and personnel from threats such as theft, vandalism, natural disasters, and terrorism. In the context of cybersecurity, physical security is crucial because even the most sophisticated digital defenses can be compromised if an intruder gains physical access to critical hardware or data storage. Effective physical security includes various strategies such as access control systems, surveillance cameras, security guards, and environmental controls to protect against fire or flooding. For example, a data center may employ biometric scanners to restrict access to authorized personnel only, while also using CCTV cameras to monitor the premises. Additionally, organizations often conduct regular security audits to identify vulnerabilities in their physical security infrastructure. By implementing robust physical security measures, businesses can safeguard sensitive data, ensure operational continuity, and protect their reputation against potential breaches or incidents.
Examples
- A bank uses armed security personnel and surveillance cameras to protect its cash reserves and sensitive customer data.
- A healthcare facility secures its patient records by using keycard access to restrict entry to authorized staff only.
Additional Information
- Physical security is a critical component of an organization's overall risk management strategy.
- Integration of physical and cybersecurity measures enhances the protection of sensitive information and assets.
